Odd seat maps and availability summer DFW
I've got a few flights booked long out into June and August, several of which have had odd seating maps displayed both on the App and online. One such example is flight 1660 on 6/29 out of DFW. The seat map in both Main Cabin and First are showing completely booked. I'm happy with my seat assignments, but am wondering what the heck is going on? I'm not on Expert Flyer, so I can't confirm seat bucket availability, but I'm shocked that two months out there isn't a single seat available on a 321. What's more, you can still book seats on 1660 (I know, not an indication of anything). Same thing for two other flights out of DFW later this summer for me.
Is this just another glitch in the system, or is something really odd occurring where the flight is indeed fully booked?
